'i ward when required for thepurpose oftipping) and` also onthevends of two iron arms marked H which n are fastened in the otherjends by an axle to the center of the hoisting carriage as seen in the drawing, but to the one side of the center of gravity of the coal car when itst-ands on the tipping carriage. To the tipping carriage these arms are fastened on the other side of the center n of gravity of the car(it being the side toward `which the car tips when unloading) thus giving to these arms, a small inclination from the perpendicular toward theside on which the car tips, these arms when the car isin a horizontal position being against the end of the scaffold F andthus held in position. a n

The blocks marked T and fastened to the tipping frame by means of levers marked n K are so arranged that when the car is at from between the wheels of the car by the ends of the levers resting on catches L, made for the purpose which raises them up,I thus leaving the car` free ready to be pushed laway, but when the car raises tothe eleva-l tion of the catches, the blocks I have dropped between the wheels of the car, and hold `it in its place while going up the shaft and while tipping or dumping. The eXtra guide A2 gives direction to the guide wheels M which being connected to the tipping carriage and frame holds them in their places while being hoisted up the shaft. These guide wheels M when the carris` being hoisted up will bear upon the eXtra guide A2 owing to the car being fas- `tenedto the iron arms as above described, and for the same reason on arriving at the top of the shaft the guide wheels n M following the curved guide N willcarry the canforward toward the dumping or tip chute 0, and the falling of the arms H while the end of the car rests on the wheels G will giveit the requisite inclination for emptying the coal or substances in the car, on the opening of the door which is effected by a small projection on the side of the chute catching the bolt of the door, and "forcing it up out of the catch.

rlhe length of the hoisting carriage is so `graduated that when the car is tipped suili- `ciently theitipping frame rests on it thus giving 'tipping ixtures a 'bearing suiicient for the requisite steadiness and also allowing them to be raised up on this position with safety should they be hoisted higher than necessary.

On returning the guide wheels M following the curved guides N throw the car and tipping carriage and fixture back in a horizontal position and the car returns to its place at the bottom of the shaft ready to be taken away and reloaded.

If a car loaded with any material not required to be dumped is hoisted, by dropping the false guides I the car is raised up in a horizontal position and by throwing out a rest marked R the hoisting carriage can be let down on it, and by ketches similar to those at the bottom of the shaft the blocks I will be raised by the levers from between the wheels of the car, and it be left free ready to be taken away on a track made for the purpose.

Vhat I claim as my invention and desire to secure by Letters Patent, is-

The combination of the coal car C, and its 25 carriage B, with the hoisting carriage D, in such a manner that whilst the hoisting carriage D, is guided 'vertically up the shaft by its ways A1, the carriage of the coal car C,

is guided by the independent ways A2, and 30 N, in such a manner as to tilt the car, when it attains the proper elevation, and place it in such a position that its contents will be self discharged into the chute O, substantially as herein set forth.
